Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to solderless electrical connections, and is particularly concerned with insulation-opening electrical con-nections and a method and apparatus for making a crimped, insulatlon-opening electrical connection.  Although prior insulation-opening connections provide a good electrical and mechanical connection, it has been found that in certain instances, a loosening effect of the connection may occur.  This is particularly a problem with stranded conductors which undergo distortion during insertion and which have a clamping pressure applied thereto by the insulation-opening contact elements.  The subsequent application of tensile forces, axially and/or transversely, to the conductor held by such pressure causes a relaxation type of def rmation and strand movement and repositioning so as to effect a drop in connection pressure.  Of course, this condition is highly undesirable and should be eliminated.  According to the present invention, an electrical connection is provided which comprises an insulated conductor which includes at least one electrical conductor within an insulating jacket, an electrical contact including an insulation-opening portion and having a contact portion which extends through the insulation into elec-trical contact with the conductor, and a section of the contact portion folded over the insulated conductor to clamp the conductor against either another portion of the contact or against a contact supporting structure.          This clamping portion is formed by crimping means, connected to the insertion member of a tool used to insert the conductor in the contact and is effective to prevent a drop in connection pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           The use of high voltage relays in variable pulse width magnetron type triggering circuits are avoided by the use of two separate pulse-forming networks.  In addition, two separate banks of charging capacitors and switching trans-formers are employed.  Separate SCR's are employed to apply charging current to either the first or the second bank of storage capacitors.  Additional SCR's are employed to initiate the triggering sequence for the selected pulse -forming network and associated circuitry.  The selected pulse length might be microsecond or one-quarter micro-second, with pulse repetition rates of 1,000 to 2,000 pulses per second.  Accordingly, the duty cycle could be in the order of 0.001?, or less, but the output pulse power during the "on" time for the circuit might be in the order of several hundred kilowatts.  During each cycle of operation, the two switching transformers and the output pulse trans-former, which are both of the square or rectangular hysteresis loop type, are reset.  Other special circuits are provided for preventing adverse interaction between the two high power pulse-forming networks and the circuitry associated with each of them.

Abstract: ABSTRACT OF THE DISCLOSURE         An industrial storage rack construction which receives cassettes, that is, elongated racks for heavy materials, in vertically arranged relationship.  The cassettes are to be in-serted in and retrieved from the rack, and the invention per-tains to the means for supporting the cassettes   This means comprises a series of rollers from front to rear of the rack at each level, supported by anti-friction bearings, and a rigid bar with a convex upper surface across the rear of the rack. The top of this bar is at a level slightly above the level of the rollers.  Each cassette is constructed with lower rails which ride on the rollers when the cassette is being inserted.  The rearward ends of these rails will ride up on the rigid bar as insertion is completed so that the cassette will be  frictionally locked in place while still being retrievable by the exertion of a relatively small withdrawing force.  The friction lock will prevent creeping of the cassette out of its bay, and in case of seismic shocks the storage rack will tend to shift under the loaded cassettes, minimizing stresses on the storage rack itself.

Abstract: CONTROL CIRCUIT FOR GENERATING A STEP-TYPE CONTROL SIGNAL AND A CONTINUOUSLY VARYING CONTROL SIGNAL WHOSE AMPLITUDE      CHARACTERISTIC REPEATS AT THE STEP TRANSITION                   ABSTRACT OF THE DISCLOSURE          A control circuit for use with an adjustable resistance to generate a first control signal whose amplitude is a function of the setting of the resistance, and which varies substantially continuously as the resistance varies, and to generate a second control signal which appears as step-like signal whose level is changed over from a first level to a second level at a predeter-mined setting of the resistance.  A pair of transistors is provided with their emitter electrodes connected in common to a reference potential and with the variable resistance coupled to the collector electrode of one transistor.  The adjustable output tap from which the first control signal is derived is connected to the base elec-trode of the one transistor.  An impedance is coupled to the collector circuit of the one transistor, and a current source is connected in common to the variable resistance and to the impedance such that the variable resistance and impedance are coupled between the collector circuit and the current source.  An output of the impedance is connected to the base electrode of the other transistor, and the second control signal is derived from the collector electrode of the other transistor, whereby as the setting of the adjustable output tap changes, the voltage applied to the base electrode of the one transistor, as well as the first control signal, correspond-ingly changes from a first amplitude toward a second amplitude until the predetermined setting is reached, whereupon the relative conduc-tivities of the transistors is reversed and the first control signal changes back to the first amplitude.  Thus, if the setting of the adjustable resistance increases from, for example, an initial setting, the first control signal correspondingly increases from a first amplitude.  When the predetermined setting is reached, the second control signal undergoes a step-wise transition, and the first control signal returns to its initial amplitude which is further increased with additional increases in the setting of the adjustable resistance.         This control circuit advantageously can be used to selectively control either of two devices, wherein one device is controlled as a function of the first control signal when the second control signal is at one level, and the other device is controlled as a function of the first control signal when the second control signal is at its other level. The control circuit also can be used to control the operation of a device over first and second operational ranges, the first range being selected when the second control signal is at its first level, and the second range being selected when the second control signal is at its second level.

Abstract: ABSTRACT     A full throttling valve is disclosed as used on a tundish having a pour tube assembly at its lower portion, a sliding gate at a midportion, and a top plate in the mounting plate beneath the vessel.  The sliding gate is shifted into position and then may be translated laterally for throttling and full shutoff.  In the full shutoff configuration the tube holder assembly may be similarly moved in and out of position in less than one minute.  Magnetic means are provided for each succeeding sliding gate coupled with the throttling mechanism to the end that successive gates may be positioned while in the throttling configuration.  Gas passageways for inert gas are provided in the top plate to prevent freezing when full throttle and shutoff occurs.  The sliding gate has an offset orifice to accommodate the full shutoff condition.          The method contemplates changing the tube holder assembley or the sliding gate with the tube holder being changed while the sliding gate is in full throttle, whereas the sliding gate can be changed in any configuration.
